Answer:
true
Step-by-step explanation:
To round off a number to its nearest whole number, look at the first number after the decimal point. If the number is equal or greater than 5, add 1 to the number before the decimal point. If it is less than 5, add zero.
Because the first number after the decimal point is 3, which is less than 5, add zero to 16 . 16 + 0 = 16
If the number were 16.571, rounding off to the nearest whole number would give 17
Find two numbers whose product is -2, and whose sum is -1.
Answer:
[tex]x=-2 \ \ \ and \ \ \ y=1[/tex]
Step-by-step explanation:
Suppose numbers are x and y
Product of x and y is -2
[tex]xy=-2[/tex]
And sum of x and y is -1
[tex]x+y=-1[/tex]
[tex]x=-2 \ \ \ and \ \ \ y=1[/tex]

PLEASE EXPLAIN HOW YOU GOT YOUR ANSWER
Answer:
errr polynomials ahaha
so basically we can multiply the power outside of the parantheses with the exponents on the inside:
so
[tex]-3x^{2*4} y^{1*4}[/tex]
this will give us:
-3x^8y^4
we also unfortunately, have to use the power on the coefficient -3 as well and we cant just MULTIPLY -3 by 4, we are going to have to multiply -3 with -3 4 TIMES(anytime we see a coefficient we MUST multiply the coefficient by itself according to the number outside of the parantheses)
so:
-3*-3*-3*-3=81
final expression
[tex]81x^{8}y^{4}[/tex]

Seven men have seven wives each man and wife have seven children what are the number of people?
Answer:
21 people
Step-by-step explanation:
given data
men = 7
wife = 7
children = 7
solution
As given each man and each wife means a couple
and they have 7 children
so
a total of 7 couples has had 1 child each
This makes it 7 Men + 7Wives + 7 Children = 21 People
Therefore
here total people is 7 Men have 7 Wives Riddle is 21 People

In which branch of statistics would a researcher acquire twenty-five 2000 Toyota Celicas, drive them until they had a major mechanical failure, record the final mileage, and then write a report for Car and Driver?
Answer:
The answer is "descriptive statistics".
Step-by-step explanation:
Descriptive statistics are short descriptive factors that add up a production set, that can be either a reflection of a whole or a sample population. It is broken down into cumulative frequency measurements and variance measurements. The study uses descriptive statistics to explain the profile of the respondents. People give simple summaries about the sample as well as the actions.

(9-3)=6
5^2=25
25*6=150
Step-by-step explanation: To handle these evaluation problems, you must be able to deal with positives and negatives, and you must know your order of operations. In addition, it's a good idea to get into the habit of using parenthses when substituting numbers in for variables.
Notice that we have a set of parenthses in our problem and remember that we use parenthses when substituting our numbers into the problem.
To avoid the confusion of having too many sets of parenthses,
let's change the parenthses in the original problem to brackets.
Now let's substitute using parenthses.
So we have (5)² · [(9) - (3)].
Since the parenthses were in the original problem were replaced
by brackets and parenthses come first in your order of operations,
in our problem the brackets are going to come first.
So first simplify 9 - 3 which is 6.
So we have (5)² [(6)].
Exponents come next so we square the 5 to get 25
and that gives us (25) [(6)] which is 150.

HELP PLEEEAAASSSE ILL GIVE BRAINLYEST
Answer:
2
Step-by-step explanation:
Answer:
2x + 19.
Step-by-step explanation:
The reasoning behind this is that one must find the disparity between the first and second expressions - 9x+14 and 7x-5. To do this, one subtracts 7x-5 from 9x+14. Set this up as though it were a normal subtraction problem - 9x+14 over 7x-5 with the little subtraction symbol to the left. When subtracting the negative five from fourteen, one adds the five to the fourteen due to the fact that the five was already negative and as such the negatives cancel out. The 7x is simply subtracted from the 9x, resulting in 2x. This leads to 2x + 19.

A man realizes he lost the detailed receipt from the store and only has the credit card receipt with the after-
tax total. If the after-tax total was $2,096.25, and the tax rate in the area is 7.5%, what was the pre-tax
subtotal?
Answer:
107.5% = 2096.25
1% = 19.5 ( divide both sides by 107.5)
100% = 1950 ( multiply both sides by 100)
pre tax $1950

find (5.3x10^3)-(8x10^2)
Step-by-step explanation:
(5.3 * 10³) - (8 * 10²)
= (5.3 * 10³) - (0.8 * 10³)
= 4.5 * 10³
= 4,500.
Answer:
[tex](5.3 \times {10}^{3} ) - (8 \times {10}^{2} ) \\ = (5.3 \times {10}^{3} ) - (0.8 \times {10}^{3} ) \\ = (5.3 - 0.8) \times {10}^{3} \\ = 4.5 \times {10}^{3} \\ = \boxed{4500}[/tex]

Answer:
(21, 0), (16, 1), (11, 2), (6, 3), (1, 4) are solutions of [tex]x + 5\cdot y = 21[/tex]. Please see the image attached below to know the plot on the coordinate plane.
Step-by-step explanation:
Let [tex]x + 5\cdot y = 21[/tex], we can determine five distinct points by transforming this function into its explicit form. That is:
[tex]x = 21 - 5\cdot y[/tex]
Then, we evaluate the function at five distinct values of [tex]y[/tex]:
y = 0
[tex]x = 21-5\cdot (0)[/tex]
[tex]x = 21[/tex]
y = 1
[tex]x = 21-5\cdot (1)[/tex]
[tex]x = 16[/tex]
y = 2
[tex]x = 21 - 5\cdot (2)[/tex]
[tex]x = 11[/tex]
y = 3
[tex]x = 21-5\cdot (3)[/tex]
[tex]x = 6[/tex]
y = 4
[tex]x = 21-5\cdot (4)[/tex]
[tex]x = 1[/tex]
(21, 0), (16, 1), (11, 2), (6, 3), (1, 4) are solutions of [tex]x + 5\cdot y = 21[/tex].
The GCF of 18, 36, and me is 2.
i am a multiple of 5.
i am greater than 18 and less than 30.
The answer is 20.
Given that,
The GCF of 18, 36, and me is 2. i am a multiple of 5. i am greater than 18 and less than 30.
Based on the above information, the information is as follows:
It should be 20 because the only 2 should be multiple of 5 that lies between 18 and 30 that are 20 andn 25But the GCF is 2 and 25 should not be divisible on the other hand 20 should be divisibleLearn more: brainly.com/question/16911495
Priya's cat weights 5 1/2 pounds and her dog weighs 8 1/4 pounds. The dog is ______ pounds heavier than the cat.
Answer:
[tex]2\frac{3}{4}[/tex]
Step-by-step explanation:
We have to subtract the weight of the cat from the weight of the dog.
[tex]8\frac{1}{4} -5\frac{1}{2}[/tex]
The first issue here is that there is not a common denominator. I'm going to multiply that 1/2 by 2 to make it 2/4. The 5 does NOT change.
[tex]8\frac{1}{4} -5\frac{2}{4}[/tex]
Subtract the whole numbers first.
[tex]8\frac{1}{4} -5\frac{2}{4} = 3\frac{1}{4} -\frac{2}{4}[/tex]
Then, we'll convert the first term to an improper fraction. We can do that by multiplying the whole number by the denominator and adding that number to the numerator.
[tex]3\frac{1}{4} -\frac{2}{4} ==> \frac{13}{4} - \frac{2}{4}[/tex]
Solve.
[tex]\frac{13}{4} -\frac{2}{4} = \frac{11}{4}[/tex]
Then, convert to a mixed number by dividing 11 by 4 and leaving the remainder in the numerator and putting the quotient in front as the whole number.
[tex]\frac{11}{4} ==> 2\frac{3}{4}[/tex]
So, the answer is [tex]2\frac{3}{4}[/tex]

Jill's weight is 92 kg 250 g. Jill's sister's weight is 8 kg 600 g less than Jill's weight. How much does the sister weigh?
Answer:
S = 83 g and 650 kg.
Step-by-step explanation:
Gram (g)= 1000 kilograms (kg).
Jill (J)= 92000 + 250 kg.
J = 92250 kg
Sister (S) = J - (8000 + 600 kg)
S = 92250 - 8600 kg
S = 83650 kg.
S = 83 g and 650 kg.
you can drive 180 miles on 1/2 of a tank of gas in 3 hours,how far can u drive on one tank of gas?
360 miles
explanation :
1 tank is 2 times as much as half a tank
so u double the half tank for a whole tank
then you double the miles you can drive on a half tank to find the number of miles you can drive on a full tank
so
1/2(2)= 180(2)
2 = 360

Step-by-step explanation:
Find the value of x.
Answer:
The value of x is 120°
Step-by-step explanation:
We should draw a line parallel to the given parallel lines and passes through the vertex of the measure x and divides it into two angles of measures x1 and x2, look at the attached figure
In the given figure
∵ The dashed line is parallel to the given line up
∴ The angle of the measure 70° and the angle x1 are alternate angles
∵ The alternate angles are equal in measures
∴ x1 = 70°
∵ The dashed line is parallel to the given line down
∴ The angle of the measure 50° and the angle x2 are alternate angles
∵ The alternate angles are equal in measures
∴ x2 = 50°
∵ x = x1 + x2
∴ x = 70 + 50
∴ x = 120°
∴ The value of x is 120°
Answer:
x= 120
Step-by-step explanation:
Alternated angles are 50 and 70
Angles of a triangle sum 180
